Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust valves, and specifically refers to a new type of combined composite exhaust valve. Background Art

[0002] Under normal circumstances, water in a pipeline will dissolve a certain amount of air. During the water flow process, the air will gradually separate from the water and gradually gather together to form large bubbles. Therefore, an exhaust valve needs to be installed on the pipeline for exhaust. Since there are impurities in sewage and the sewage composition is complex, it will cause corrosion to the internal parts of the valve. If the impurities enter the valve port, it will affect the seal, and even block the valve port and cause obstacles to operation. Therefore, the valve port must be far away from the sewage, and the material of the internal parts of the valve should be corrosion-resistant. When trace amounts of combustible gases are generated in the sewage medium and are not easily discharged, it will pose a safety hazard. Content of the Utility Model

[0003] To solve the above existing problems, the utility model provides a new type of combined composite exhaust valve in which other waste water and other particulate matters will precipitate under the float ball and be discharged through the bottom sewage outlet; the design of the lengthened connecting rod separates the liquid from the sealing mechanism, ensuring the stable operation of the exhaust valve, being easy to assemble, and easy to achieve mass production.

[0004] The technical solution adopted by the utility model is as follows: A new type of combined composite exhaust valve of the utility model includes a lower valve body, an upper valve body, a valve core, a lengthened connecting rod and a float ball. The upper valve body is connected to the lower valve body. The lower end of the lower valve body is provided with a water inlet. The upper valve body is provided with a large exhaust port penetrating the upper valve body. One side of the lower end of the lower valve body is provided with a sewage outlet. The valve core is arranged in the upper valve body. The float ball is arranged in the lower valve body. The two ends of the lengthened connecting rod are respectively fixedly connected to the valve core and the float ball. The valve core includes a float and a sealing cover. The float slides in the upper valve body. The sealing cover slides in the upper valve body and is arranged above the float. The sealing cover is connected to the float. A micro-exhaust port is arranged in the sealing cover.

[0005] Further, a connecting rod bracket is fixedly arranged at the upper end of the lower valve body, and a connecting sleeve rod is fixedly arranged below the connecting rod bracket. The connecting sleeve rod is arranged in the lower valve body and sleeved outside the lengthened connecting rod.

[0006] Further, a connecting bracket is fixedly arranged below the sealing cover. The connecting bracket is arranged in a U shape. Two guiding slide rails are symmetrically arranged on the side wall of the float. The connecting bracket slides in the guiding slide rails.

[0008] Further, a connecting flange is provided at the connection of the lower valve body and the lower valve body, and the connecting flange is fixed by screws, so as to connect the lower valve body and the lower valve body together.

[0009] The beneficial effects achieved by the present utility model with the above structure are as follows: By reforming the internal structure, the micro-discharge function is increased. When the valve cavity is under high pressure, the large exhaust port is closed and cannot be opened, and the generated tiny gas is discharged through the micro-discharge port to ensure system safety; When the system starts to fill and drain water in the empty state, the air valve quickly discharges and inhales a large amount of air in the pipeline; When the system is under pressure, it can effectively discharge a small amount of air and other gases in the pipeline, and other waste water and other particulate matters will precipitate under the float ball and can be discharged through the bottom sewage outlet; The design of the lengthened connecting rod separates the liquid from the sealing mechanism, which can ensure the stable operation of the exhaust valve.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0015] Such as Figures 1 to 3As shown in the figure, the novel combined composite exhaust valve proposed by this solution includes a lower valve body 1, an upper valve body 2, a valve core 3, an extended connecting rod 4 and a floating ball 5. The upper valve body 2 is connected to the lower valve body 1. The lower end of the lower valve body 1 is provided with a water inlet 6. The upper valve body 2 is provided with a large exhaust port 7 that penetrates the upper valve body 2. One side of the lower end of the lower valve body 1 is provided with a sewage outlet 8. The valve core 3 is arranged in the upper valve body 2. The floating ball 5 is arranged in the lower valve body 1. The two ends of the extended connecting rod 4 are respectively fixedly connected to the valve core 3 and the floating ball 5. The valve core 3 includes a float 9 and a sealing cover 10. The float 9 slides in the upper valve body 2. The sealing cover 10 slides in the upper valve body 2 and is arranged above the float 9. The sealing cover 10 is connected to the float 9. A micro-exhaust port 11 is arranged in the sealing cover 10.

[0016] Among them, a connecting rod bracket 12 is fixedly arranged at the upper end of the lower valve body 1. A connecting sleeve rod 13 is fixedly arranged below the connecting rod bracket 12. The connecting sleeve rod 13 is arranged in the lower valve body 1 and sleeved outside the extended connecting rod 4. A connecting bracket 14 is fixedly arranged below the sealing cover 10. The connecting bracket 14 is arranged in a U shape. Two guiding slide rails 15 are symmetrically arranged on the side wall of the float 9. The connecting bracket 14 slides in the guiding slide rails 15. An anti-detachment card slot 16 is arranged at the lower end of the guiding slide rail 15. An anti-detachment buckle 17 is arranged on the inner side wall of the lower end of the bracket. The anti-detachment buckle 17 is clamped in the anti-detachment card slot 16. A connecting flange 18 is arranged at the connection between the lower valve body 1 and the lower valve body 1.

[0017] During specific use, when the pipeline is filled with water, a large amount of internal air passes through the channel between the upper valve body 2 and the valve core 3 and is discharged at high speed through the large exhaust port 7. After the air in the pipe is exhausted, as the water level rises, the floating ball 5 drives the valve core 3 to rise through the extended connecting rod 4, so that the sealing cover 10 in the valve core 3 rises to the large exhaust port 7. Under the action of buoyancy and water pressure, the float 9 is also pushed up, so that the float 9 moves along the connecting bracket 14 until the float 9 completely fits with the sealing cover 10, realizing zero-leakage sealing. The air wrapped in the water by the turbulence in the pipeline slowly precipitates and accumulates in the upper valve body 2. The air pushes the liquid level down, and the float 9 moves down along the connecting bracket 14 and separates from the sealing cover 10. The air is discharged through the small exhaust port in the sealing cover 10, and the micro-exhaust system can continuously discharge.

[0018] When a water cut-off fault occurs in the pipeline and the water level drops rapidly, the floating ball 5 drives the valve core 3 to drop. At this time, the sealing cover 10 separates from the large exhaust port 7, and a large amount of air enters quickly, preventing siphon and damage to the pipeline due to negative pressure.

[0019] The floating ball 5 is connected to the valve core 3 through an extended connecting rod 4. Under the dual action of buoyancy and gravity, it drives the valve core 3 to move up and down, realizing the functions of exhausting, admitting air, and micro-exhausting. By modifying the internal structure, the micro-exhaust function is added. When the valve cavity is under high pressure, the large exhaust port 7 is closed and cannot be opened, and the tiny gas generated is discharged through the micro-exhaust port to ensure the safety of the system. When the system starts to fill and drain water in the empty state, the air valve quickly discharges and inhales a large amount of air in the pipeline. When the system is under pressure, it can effectively discharge a small amount of air and other gases in the pipeline. Other waste water and other particulate matters will precipitate under the floating ball 5 and can be discharged through the bottom sewage discharge port 8. The extended connecting rod separates the liquid from the sealing mechanism, which can ensure the stable operation of the exhaust valve. It is easy to assemble and easy to achieve mass production.
